Terrorist attack is one of the biggest threats to the safety of human beings living on the planet, United States is not an exception. The analysis on the United States terrorist attacks was conducted based on the data collected in the Global Terrorism Database throughout a timespan from year 1970 to 2016. Notorious terrorists use different attack weapons when they are committing attacks. This paper explores what type of weapons used are most deadly in US terrorist attacks, so that governments will be able to better prevent and recover from the attacks from those weapons.

How many terrorist attacks happened in States from 1970 to 2016?

It is clear that California and New York experience the most terrorist attacks with a number of 586 and 504 incidents respectively.

What are the two most attack weapons in California and New York states?

Selecting the states that experienced the highest number of attacks, California and New York, a further analysis about the different weapons used is conducted.

Explosives and incendiary weapons are most frequently used in California and New York terrorist attacks, followed by Firearms and Melee. In the 1970 to 2016 time period, California experienced more terrorist attacks than New York, so the frequency for each weapon used in California is higher than that in New York.

Which weapons are more deadly?

The most frequently used weapons are not necessarily the most damaging. Therefore, analysis based on the deceased casualties for each weapon category is conducted. The ratio of deceased casualties was calculated by death amount divided by the sum of death and injured amount. The graph shows that, even though explosives and incendiary weapons are used the most, they are actually much less deadly than firearms. Moreover, the firearms used in New York caused a greater proportion of deaths than in California, while the opposite is true for explosives and incendiary weapons. It is important that the government closely regulates firearm use.

From the analysis in states that experienced the most terrorist attacks, it is found that the most used weapons in those two states are explosives, incendiary weapons, and firearms. However, the most deadly weapon is firearms. The data also shows an increasing trend of firearm use in terrorist attacks in recent years. Therefore, the government should set more effective regulations to firearm usage and educate citizens on how to deal with attacks that involve firearms.
